The present invention pertains to a novel direction indicator for vehicles, particularly motor vehicles.

The principal object of the invention is to provide a device of this character which may be mounted at the sides of the vehicle and operated in accordance with the direction in which the vehicle is about to turn. The de-Y vice comprises essentially an elongated slidable member, preferably pneumatically op-V erated, carrying another member movable therewith as well as relatively thereto. The y' relative movement occurs at the end of the contemporaneous movement as is utilized to actuate pivoted indicating arms carried byv the movable members. n v vThe invention is fully disclosed by way ofA example in the following description and inthe accompanying drawings in which y p Figure 1 is a longitudinal section of the y device in idle position;

Figure 2 is asimilar section of the deviceV in semi-operative position Figure 3 is a detail elevation of the device'. 25 in operative position;

Figures 4 and 5 are sections; f

Figure 6 is a similar detail section 1n aV different but parallel plane;

Figure 7 is a detail longitudinal ysection at right angles to Figure 6; n

Figure 8 is aV section on the line 8-8 of Figure 6; Y

Figure 9 is a longitudinal section of theY valve; and Y Figure 10 is a section on the line 10-10 of Figure 3. Reference to these views will now be made by use of like characters which are employedI to designate corresponding parts throughout.` With reference first to Figures 1, 2, 3 and 4 it will be seen that the device comprises two tubes l and 2, preferably of equal length, Y

Vjoined together in alinement .by -being threaded on a plug 3.V A piston 4 is slidably mounted in the tube 2 and is carriedI on a piston rod 5 passing through the plug3.-k

The latter is fitted with a packing nut 6 surrounding the rod 5 to preventleakage.

[serial No. 472,24. n l y through the plug, vras shown -moreclearly in rifare 5.: f p y 4 Y The rod isconnectedto the indicating members by means of linkage consisting of parallel k"strips or 'slats' 7 between which is slidably mounted an intermediateX guide strip 8.V The member 8 is of the same length Yas the tube 1 while the strips7 are shorter, as may be Vseen byY the extremities 71of the `latter shown in Figure 2 and theguide 8 is secured to the strips 7 byrivets 9..,

' VThe guid"`8 has aV frame-'likeinner end 10 Vand is further slotted Lkas vat 11V throughout its entire length. The 'endr 10 is joined tothe piston Vrod by pins 12 as clearlyshown in v `'Figures 6 and 7. AIn the slot 11 is'slidably 'mounted a link`13 having 'a headl 14 `disposed lin the frame-like end 10 ofthe member 8. A pin 15 held rigidly in the-head ltis adapted to moveslotsl in the lateralstrips7 as will presently appear; A spring 17 received in the end 1Q andbears against ksaid endv and the head 14 andends of members 7 `as shown in Figures6 and 7;

The outer end of the guide 8 has 'a pair of indicating arms 18pivoted thereto on pins 19` and adapted to swing outwardly in opposite directions as shown by the arrows in'Figure 2. Al/Vhen turned inwardly, theyv engage the `ends 7" of the members 7 as also shownin this ligure. A pin 2OA fixed in the link 13 is received in'lnotches or'slots 21 in the pivoted ends ofthearms 18.

For controllingtheoperation ofthe device, i

there is provided: a two-'way valve of the type shownin Figure 9. Acyli'nder 22:'has a pressure intake port 23 `and two outlet portsf24 'Y and 25 with which the port 23 may be selec tively connected. rod 26 having :fanl ,eX-i terior operatinghandle 27 is slidably mount-VY ed in tliecylinder land carries pistons28 Yand 29 also slidable'inlthe cylinder. Thepistons are so spaced as to obstruct th'e'intakeport 23 from either ofthe Youtlet yports 24 and 25,r while theother outleti'portis in communication witlrthe intake port. vA spring 29 between the' closed end of the cylinder `and the piston 28 no-rmally'holdsthe piston rod in the.,.-positiony connectingtheiports 23 andi.:

It will be understood that Vsuction may be used as Well as pressure, and the connections interchanged accordingly.

0n application of pressure or suction to the device by the means already described, all parts Within the tubel 1 will be extruded therefrom uniformlyby movement of the rod 5, tothe position. shown in Figure 2, until the pin, 15, engages the outer end wall of the c-vlinder 1' 'as shownv in Figures 4, 6 and 7. The

link 13 is thusl held against further ;move

nient, but the lateral members 7 are free to lmove the length ofthe slots 16 as may be seen by reference to Figure 7.V Hence, further movement of' the piston rod 5 actuates the members 7fin this manner through the spring 17 L It will be recalled that the pin 2O is fixed relatively t0 the link 13, and consequently the continued outward movement of the A lateral members 8 carries the pivot points 19- indicating member pivoted to said elongated member and having a connection with said link member, whereby to be swung by relative movement of said members, a slidable rod for actuating said members, a spring connection between said rod and link member,

and a slot-and-pin connection between said members for permitting said relative move- Vment therebetween.

In witness whereof I have hereunto set my hand. Y .i

--Two devices of the character described are mounted on the'vehicle, one at each, side. A contemplated turn ofthe vehiclein either direction is indicatedl by? operating the device on the correspoi'iding side., Y

Although. a specific embodiment, of' the invention has been` illustrated and described, it.

will be understood that various. alterations in thel details of construction may be made without departing from; the Scope ofthe invention asfindicatedby the appended claims.

What I claim is 1. A direction indicator for motor vehicles comprising a housing, an elongated member slidable through one endthereof, a link memy ber movable with said elongated member and adapted" for movement relatively thereto, an

indicatingfar'm pivotedto'one of saidv meinbers and having a connection with the other ,'member,l whereby to be swung by relative "movement of-said members, a'slidabl'e rod 'for actuating said members, and spring connection` between said rod and one of saidv members, andl ajslot-andepinconnection be tween. saidfmembers fo-r'permitting said rela-` tivefmovement therebetween.
